To all whom it may concern Be it known that I, Gnoncn H. JENKINS, acitizen of the United States, residing at Oak Park, in the county ofCook and State of Illinois, have invented certain newand usefulImprovements in Books and Binding Devices Therefor, of which thefollowing 18 a specification.

This invention relates to a bound book such as results from bindingloose leaves into permanent form, and also to the means by which suchbinding is elfected.

Among the principal objects of my invention is the provision of abinding, secure, inexpensive and capable of being performed by any oneunskilled in such matters; and a permanent binding of loose leavescapable of being efiected while still retalned wltlnn current ortemporary covers.

It is common practice in business records to utilize a quantity of looseleaves securedbetween current covers and to add from time to time to thebook thus formed as additional leaves are required. It is usual totransfer the contents of such abinder to another pair of covers and bindthe same permanently therein. The book thus formed may then be filedaway as a permanent record. The meansheretofore employed for elfecting atransfer of loose leaves from current covers to permanent covers hasusually involved considerable expense and skilful manipulation' In'thepresent invention I have sought, therefore, to ClQVlSGZL construction ofbinder which enables a transfer of leaves in the most expeditious andeconomical manner.

In the drawings: Figure 1 is a crosssection through a quantity of leavesbetween permanent and current covers as arranged at the time apermanentvbinding is to be performed; Fig.2 is a cross-section throughone end of a book completely bound Fig. 3 is a view similar to Fig. 2,showing a modified form of binding; Fig. 4: is a side elevation of thebook showing a slightly different relation of the parts during thebinding operation than is exhibited in Fig. 1; Fig. 5 is a plan view ofa quantity of unbound leaves arranged between clamps to facilitate thebinding operation; Fig. 6 is a cross-section on line 66 of Fig. 5; Fig.7 is a view similar to Fig. 5, showing a modified form of clampconstruction; and Fig. 8 is an end elevation showing the constructionexhibited in Fig. 7.

Fig. 1 represents a quantity of leaves 9 bound together for current usebetween covers 10. Posts 11, provided with screw caps 12, areillustrated as an appropriate binding for this purpose. The covers 10differ from those ordinarily employed chiefly in that a number ofopenings 13 are provided in the plane of binding.

At the time a permanent binding is to be performed, it is contemplatedthat permanent covers 14 shall be arranged in position as shown in Figs.1 and 1. Ordinarily one of these permanent covers is laid adjacent oneof the current covers at the time the leaves are first inserted in thebook, so that when a permanent bindingis to be effected it is necessaryonly to remove the temporary cover which lies adjacent the threaded endof the postin order to install the other permanent cover in place. Iwould have it understood that it isnot necessary to replace in positionthe current cover 10 which was removed to allow positioning of thesecond permanent cover, asmight be inferred, perhaps, from Fig. 1, butthat the binding may be performed as well by compressingthe leavesthrough the medium of the caps which screw upon the posts 11 pressingdirectly against the permanent cover as shown in Fig. a.

When the leaves are arranged between the permanent covers in this mannerand the desired compression is obtained, I contemplate driving a numberof nails 15 or other pointed elements into the leaves. The places atwhich these nails are driven may be determined by the openings 13, whichare of suliicient size to enable the nail head 16 to pass therewithin.The permanent covers need not have such openings, but may, if desired,be marked to indicate advantageousv positions in which these nailsshould be driven, or, in lieu of such marks, be provided with smallholes to facilitatedriving' in of the nails. As will appear from Fig. 1,these nails should be of suificient length not to pass through theentire stack of leaves, but rather that their shanks should overlap tosome extent through the central portion of the book when the nails aredriven in from opposite sides thereof.- Also, I prefer to group theplaces at which the nails shall be driven, so that the pressure causedby displacement of the material as each nail forces its way through thebook will cause a slight increase in frictional pressure against theadjacent nail, thereby effecting a tighter and .more secure binding.

In Fig. 3 is shown the use of nails 15 to bind leaves together which areslightly longer than the width of the book. In this instance it isnecessary to clench the nails, as shown in the said figure; otherwisethe binding is the same as the other forms shown and described.

It is apparent when the leaves composing the book have been permanentlysecured between the covers that the screw caps may be removed from theposts and the temporary covers be withdrawn to be again available foruse with other leaves. The, bound book is held together between thepermanent covers solely by frictional engagement of the nails within theleaves. It is possible, of course, that the nails might have a tendencyto loosen and withdraw, in which. case the binding would eventually bedestroyed. To prevent this, as well as to give the book afinishedappearance, I contemplate adhering or securing to the back ofthe book and the adjoining edges of the covers a strip offlexiblematerial, such as the backing 17 shown in Figs. 2, 3 and 4:. Forconvenience this backing may be initially secured to that permanentcover which was first installed Within the current 7 covers, so that atthe time the said current covers are removed one end of this backing isall ready to be secured in place. It is manifest, therefore, that thepresence of this backing which overliesthe adjacent edges of thepermanent covers, and is secured thereto, resists effectually anytendency for the binding of the leaves to become loosened and destroyed.

In Figs. 5 to 8, inclusive, are shown leaves bound permanently togetherby the same means as is illustrated in the other figures.

vIn theselatter figures, however, theleaves are not secured initiallywithin any binder, but are loose and unboundat the time they arearranged for binding. For this purpose I provide a pair of clamps 18 atthe extremities of which posts 19 and screw caps 20 are so arranged asto compress between the clamps a stack of leaves to be bound. Theseclamps are provided with openings 13 simi-' lar to those shown in Fig.1, through which the nails thatefiect the binding are driven.

In order to accommodateleaves of different Widths and to prevent bendingor spring ing of the plates, I arrange intermediate the posts 19 one ormore lips 21 intermediate the ends of the plate which project out justbeyond the edge of the leaves to be bound. Throughthis lip a threadedpost and cap extend, similar to that'employed elsewhere, so that acompression of the leaves inter mediate the ends thereof may easily beeffected. This form of clamp construction is clearly shown in Figs. 7and ,8. After the nails are driven to secure the leaves and permanentcovers together, I contemplate the application of a flexible backing inthe same manner as is illustrated in Figs. 2

and 3.

I have usedthe term nail to designate the element which permanentlysecures the leaves in bound form. Ordinary pointed nails or threadedscrews will answer equally well the purposes of this invention. If pre-'ferred, short holes may be drilled in the leaves to facilitate drivingin of the nails or screws, but the use of such an expedient is entirelyoptional with the operator.

I claim: I r I 1. In combination with a quantity of leaves arranged inbook form, a pair of clamping elements between which the leaves are heldtogether, means for maintaining said elements in clamping relationlocated outside of the book body, said clamping elements being providedwith a plurality of openings through each of which a pointed element maybe driven to effect a binding of the leaves, said clamping elementsbeing removable from the book without interference with said bindingelements.

2. In combination, with a quantity of leaves arranged in book form, apair of clamping elements between which the leaves are held together,means located outside of the book body for maintaining said elements inclamping relation at a point intermediate the ends of the bound edge ofthe book, said clamping elements being provided with a plurality ofopenings througheach of which a pointed element may be driven to effecta binding of the leaves, said clamping elements being removable from thebook without interference with said binding elements.
